J Androl. Existing cases of diabetic retinopathy become more pronounced during pregnancy, usually in the final trimester, and require treatment. Renal function should also be examined. It is also crucial that the blood sugar levels are optimally managed. As with all women who wish to get pregnant, specialist associations recommend beginning with iodine and folic acid tablets before the pregnancy.

Beginning at least 4 weeks before pregnancy and continuing until the end of the 12th week of pregnancy, women should take between 0. At least milligrams of an iodine prophylaxis supplement should be taken.

Information on iodine-rich food and the use of iodized salt is recommended. The aim is to ensure the fetus receives enough iodine and to prevent thyroid-related complications.

In cases of unwanted pregnancy, women with diabetes should seek medical advice as soon as possible. It may be necessary to adjust diabetes therapy before pregnancy. For women with type 1 diabetes , this may mean that their doctor recommends switching to another type of insulin preparation.

For women with type 2 diabetes , medical specialists recommend switching to insulin therapy. As with all types of medication, care should be taken during pregnancy.

For many types of blood sugar-reducing medications , there is little data available on their safety for the unborn child. For this reason, doctors recommend switching to insulin therapy human insulin before a planned pregnancy.

Intensified insulin therapy or an insulin pump are used. In some cases, it is possible to get blood sugar levels under control through lifestyle changes, sufficient exercise and a healthy diet. Finding the correct insulin dosage is not always easy.

On top of this, any change in treatment can cause often uncertainty. For this reason, women with type 2 diabetes should take part in a course to learn how to inject and measure blood sugar levels correctly. There they will learn to use an insulin pen or insulin pump.

The costs for the course are usually covered by the health insurance provider. Find out more about insulin therapy here! It is recommended that pregnant women measure their blood sugar levels 6 times per day 1 hour before each meal, and 1 hour after.

A safe and reliable blood sugar measurement device should be used for blood sugar self-testing. Blood sugar levels and insulin requirements change during pregnancy up until delivery due to the pregnancy hormones.

During the 1st trimester, the amount of insulin required falls. During this period, the expectant mother must inject less insulin to prevent low blood sugar levels. The insulin requirements increase rapidly during the 2nd trimester and then dramatically fall again after giving birth. During the 1st trimester, there is an increased risk of low blood sugar hypoglycemia , especially during the night.

To help estimate the risk of nocturnal low blood sugar, blood sugar levels can be tested at around 11 pm. The diabetes specialist responsible for treatment must carefully adjust the insulin dosage.

Pregnant women should definitely inform those close to them and their partner about what to do in the event of severely low blood sugar levels.

Ketoacidosis acid buildup in the blood caused by lack of insulin associated with pregnancy diabetes is an emergency situation. Expectant mothers discuss with their diabetes specialist at what blood sugar level they should begin testing acetone levels in the urine.

To ensure good management of type 1 or type 2 diabetes during pregnancy, the patient should attend the following check-ups, among others:. If the blood sugar levels are too high throughout pregnancy, the child can become too large and too heavy birth weight exceeding grams.

This can lead to complications during birth or cesarean section. Diabetes-related complications, e. During the later stages of pregnancy, expectant mothers can develop high blood pressure. In this case, self-testing of blood pressure can be carried out on a daily basis.

Pregnant women with diabetes are more likely to develop infections of the genital and urinary organs, which can lead to premature birth. For this reason, regular testing is recommended.

Preeclampsia, also known as gestosis or pregnancy poisoning, is especially serious. It is characterized by high blood pressure and increased excretion of protein via the urine proteinuria. Preeclampsia, the most severe form of gestosis, is a very serious emergency situation that requires immediate hospital treatment.

Women with type 1 diabetes in particular can develop low blood sugar levels during the 1st trimester, especially at night. Therefore, it may be necessary to temporarily change or adjust their course of treatment.

Later in pregnancy, the blood sugar levels become more stable and the risk drops. The internal organs of the fetus develop during the 1st trimester of pregnancy. If the blood sugar levels are not optimally regulated before and during pregnancy, this can result in malformation of the heart, nervous system, and lungs in particular.

Miscarriage and premature birth are also possible. The risk of premature birth birth before the end of the 37th week of pregnancy is on average 5 times higher for expectant mothers with diabetes. These risks can be significantly reduced thanks to targeted consultation, good metabolic management, and blood sugar self-testing.

Other typical complications include low blood sugar, jaundice hyperbilirubinemia , or respiratory disorders.

Around 5 percent of children from mothers or fathers with type 1 diabetes will also develop diabetes mellitus, because the disease is partially genetically determined.

Hyperglycemia and fertility -

DM2 patients were not subdivided according to duration of illness to avoid bias related due to age-related disease. This is because DM2 occurs temporally after DM1 and all patients enrolled were in childbearing age.

DM2 patients reported a previous nonalcoholic steatohepatitis returned after weight loss. All enrolled subjects did not smoke, drink alcohol, and did not use drugs. All methods were performed in accordance with the relevant guidelines and regulations. All participants were asked for and provided their informed consent.

Oxidative stress evaluation in the seminal fluid was executed by measuring the degree of mitochondrial superoxide and the degree of LP. Seminal analysis of each sample was replicated as reported by the WHO guidelines.

Semen samples were collected by masturbation into a sterile container after 2—7 days of sexual abstinence and were transported to the laboratory within 30 min after ejaculation. Each sample was evaluated for seminal volume, pH, viscosity, sperm count, progressive motility, morphology, and round cell concentration spermatids and leukocytes according to the WHO criteria The debris was gated out, by drawing a region on forward vs.

side scatter dot plot enclosing the population of cells of interest. Computed compensation was made before performing all the analyses. The damage of MMP is an early event of the apoptosis and it is reversible. JC-1 is able to penetrate selectively in mitochondria and it exists in monomeric form, emitting at nm; following excitation at nm and in relation to the membrane potential, JC-1 is able to form aggregates emitting at nm.

The fluorescence changes reversibly from green to orange as soon as the mitochondrial membrane becomes more polarized. Therefore, it is possible to distinguish two cell populations: cells with damaged MMP where JC-1 remains in the cytoplasm in a monomeric form, giving a green fluorescence and cells with normal MMP with a double fluorescence where JC-1 in addition to emitting green in the cytosol is also in the mitochondrial membrane in form of aggregates emitting in an orange fluorescence.

At the end of the incubation period, the cells were washed in phosphate buffered saline PBS and analyzed by the detectors FL1 and FL3. The evaluation of chromatin integrity was performed after permeabilization of the cell membrane, to allow the access of the fluorophore within the nucleus.

An aliquot of 1 × 10 6 spermatozoa was incubated with LPR DNA-Prep Reagent containing 0. Flow cytometric analysis was performed after 30 min, using FL3 detector. The externalization of phosphatidylserine PS on the outer cell surface is an early signal of apoptosis. The assessment of PS externalization was performed using annexin V, protein that binds selectively to PS in presence of calcium ions, FITC-labeled.

During apoptosis, the cells exhibiting the PS even before the loss of semipermeability. Therefore, marking simultaneously the cells with annexin V and PI, we could distinguish: alive with intact cytoplasmic membrane , apoptotic, or necrotic cells.

An aliquot containing 0. After incubation, the sample was analyzed immediately by the detectors FL1 FITC and FL3 PI. The different pattern of staining allowed to identify the different cell populations: FITC negative and PI negative indicate viable cells, FITC positive and PI negative indicate cells in early apoptosis with cytoplasmic membrane still intact, and FITC positive and PI positive indicate cells in late apoptosis.

The evaluation of DNA fragmentation was performed by the TUNEL method. This uses the Terminal deoxynucleotidyl Transferase TdT , an enzyme that polymerizes, at the level of DNA breaks, modified nucleotides conjugated to a fluorochrome.

The TUNEL assay was performed by using a commercially available kit DBA s. To obtain a negative control, TdT was omitted from the reaction mixture; the positive control was obtained pretreating spermatozoa about 0. The debris was gated out as described above. The reading by threshold-setting method was performed by flow cytometry using the FL1 detector.

This displacement of the emission is shown by the flow cytometer which provides an estimate of the degree of peroxidation. LP was evaluated in two different sperm aliquots of the same patient: the first consisting of spermatozoa separated by swim-up and the second obtained by centrifugation of the seminal fluid raw semen.

About 2 × 10 6 of spermatozoa were incubated with 5 mM of the probe for 30 min in a final volume of 1 ml. After washing with PBS, flow cytometric analysis was conducted using the FL1 and FL2 detectors. Mitochondrial superoxide levels were detected by the MitoSOX red mitochondrial superoxide indicator Invitrogen, Thermo Fisher Scientific, Eugene, OR, USA This probe, once penetrated into the mitochondria, is quickly oxidized by superoxide anion not from other free radicals and as a result of this process, the probe becomes highly fluorescent with signal detection.

About 1 × 10 6 of spermatozoa were incubated with 5 µM of the probe for 10 min in a final volume of 1 ml and at a temperature of 37°C. After washing with PBS, flow cytometric analysis was conducted using FL1 detectors.

Specifically, after liquefaction, three aliquots of µl of seminal fluid underwent to three washing cycles with PBS. After elimination of the supernatant, the pellet was resuspended in 1 ml of PBS.

All patients underwent didymo-epididymal ultrasound evaluation using a linear 7. Ultrasound evaluation of the testicular volume and epididymal diameters was performed, before and after ejaculation, by the same clinician SLV. The ultrasound parameters evaluated were epididymal caput CEAE and tail TEAE after ejaculation, testicular volume VT , cranial CEBE , and caudal TEBE diameter before ejaculation.

The operator repeated twice the measurement of these parameters are expressed as mean on the final report. Blood sampling was performed at 8.

Determination of LH, FSH, and TT serum levels was performed by electrochemiluminescence immunoassay with Cobas equipment. The results are expressed as mean ± SEM throughout the study. SPSS Statistical significance was accepted when the p value was lower than 0.

The anthropometric parameters of the patients enrolled in this study are shown in Table 1. DM patients showed no statistically significant differences in age, BMI, and waist circumference compared to controls Table 1.

Table 4. Hormone concentrations of patients with type 1 diabetes mellitus DM1 , type 2 diabetes mellitus DM2 , and the control CTL group. The results of this study showed that diabetic patients in childbearing age have alterations of conventional sperm parameters compared to non-diabetic controls.

Of particular, the main alterations concern sperm concentration, progressive motility, and normal forms. Patients with DM1 showed a progressive motility that significantly deteriorated alongside the duration of the disease. Previous studies did not show significant variations of this parameter and no correlation with age, disease duration, or HbA1c levels 8 , By contrast, other studies confirm our data showing a decrease in sperm progressive motility in patients with DM1 and DM2 28 and in 32 DM1 teenage patients Mitochondrial membrane potential is the main parameter that better reflects mitochondrial function, which regulates sperm motility.

An association between decreased sperm progressive motility and an increase in the percentage of spermatozoa with low MMP has been shown in both groups of diabetic patients compared to controls. Other studies have shown that mitochondrial ultrastructural alterations are associated with a decreased sperm motility 30 , In patients with DM1, the alteration of the mitochondrial function became evident in patients with a disease duration ranging between 5 and 10 years, whereas the alterations of sperm progressive motility became significant in patients with a disease duration greater than 10 years.

Therefore, mitochondrial alteration seems to anticipate the subsequent and physiological decrease in sperm motility. Sperm volume was lower in patients with DM2 although the difference did not reach the statistical significance, unlike to previously published data This discrepancy may relate to the fact that patients with DM2 enrolled by Ali and colleagues 28 had lower TT values than the control group.

In addition, patients with DM2 enrolled in the present study were younger, in childbearing age and not yet entirely affected by the age-related androgenic decline compared to those described in the literature.

These DM2 patients enrolled had normal TT levels but higher values of LH compared to controls to indicate an initial testicular alteration. So, this slight reduction of the sperm volume may, however, represent the beginning of a process that could worsen at a later age.

Instead, DM1 patients showed lower seminal fluid volume in the presence of normal blood circulating concentrations of androgens. The patients of our study have bigger epididymal head and tail diameters after ejaculation compared to controls, suggesting an alteration in the epididymal contractile function.

This phenomenon, indicative of a dysfunctional epididymal voiding capability, may be the cause of the decreased seminal fluid volume observed in these patients. Leukocytes present in the rete testis, vas deferens, and human ejaculate are predominantly T-suppressor lymphocytes The role of lymphocytes in the seminal fluid is not only antimicrobial but also to remove apoptotic or immature germ cells.

The presence of these lymphocytes could improve seminal quality because T-suppressor lymphocyte removal action would avoid the activation of T-helper lymphocytes against antigen-presenting cells decreasing the production of antisperm antibodies and their possible sperm damage Therefore, this could explain the increased percentage of T-suppressor lymphocytes in DM2 patients, where there is a greater number of apoptotic cells, while that of T-helper is decreased because of the absence of microbial agent and antigen-presenting cells.

With regards to oxidative stress indices, the mitochondrial superoxide anion concentration was found to be higher in DM2 than in DM1 patients.

Indeed, LP increases only in DM2 patients, especially in relation to the higher concentration of seminal fluid leukocytes of this group of patients. In DM2 patients, the increase of LP and mitochondrial superoxide anion may decrease MMP and consequently be responsible for a greater sperm motility decline than in DM1.

Recently, it has been shown that the epididymis is a potential target of the oxidative stress in diabetic patients. Immunohistochemical analysis has shown the presence of AGE receptors in this organ In addition, malonildialdehyde levels, the final product of LP, are higher in DM2 patients compared to controls 5 , 6.

These data are relevant to understand the physiopathological and clinical aspects that can address a more targeted and specific therapeutic approach.

In addition, a greater percentage of DM2 patients are less vital, in late apoptosis and with fragmentation of sperm DNA. These data, associated with an increased number of leukocytes in the seminal fluid, with an increased LP and levels of mitochondrial superoxide, indicate that oxidative stress is the leading cause of impaired sperm quality of DM2 patients.

Finally, the didymo-epididymal ultrasound evaluation revealed a lack of physiological contraction of the cranial and caudal portion of the epididymis after ejaculation in DM1 patients.

Conventionally, the ultrasound epididymal thickness decreases by approximately 3 mm after ejaculation, as found in DM1 patients with a duration of illness of less than 10 years.

Epididymal cranial and caudal tracts are characterized by a spontaneous peristalsis that can also carry immotile spermatozoa The caudal portion of the epididymis has a rich adrenergic innervation, which is activated during ejaculation.

Adrenergic denervation does not eliminate epididymal contractility This suggests that the contractility is mediated by a neuronal mechanism and other hormonal oxytocin and endothelin 1 and non-hormonal factors, which can alter the contractile function of the epididymis.

Type 1 diabetes mellitus patients have low ejaculate volume due to a lack of physiological epididymal contraction associated with mitochondrial damage that anticipates the subsequent decline of sperm progressive motility.

These findings are associated with an increased oxidative stress that can also alter other conventional sperm parameters, although to a lower extent than in DM2 patients. Type 2 diabetes mellitus patients, instead, seem to be characterized by an amicrobial inflammatory condition and increased concentration of seminal fluid leukocytes, which raises oxidative stress indices damaging conventional sperm parameters, sperm DNA, and vitality.

Since diabetic disease affects male fertility, the prevention of DM2 and the follow-up of seminal parameters in DM1 should be recommended in patients in childbearing age.
