If this does not work, the only option is testicle transplant. They use 1 testicle and one silicon rubber mockup, so they can help 2 people from each pair of balls removed.

Pig testicle is also possible. It is cheaper and no waiting list, but only do in asian countries except malaysia and indonesia.

Some wifes report change in flavour of semen, and excessive volume of semen, and obviously you cannot have babies with pig testicle. I am kind of confused on the 2.

Does your body only disperse a certain amount of sperm per ejaculation???? I am the opposite of folks here… I do not want any pregnancy, but my partner decided she is all set with any sort of birth control.

I stopped taking them altogether 8 days ago to give myself and my wife the best chance of improving sperm morphology and, in turn, conceiving.

Any help or advice would be appreciated. If one ejaculates a lot is there possibility that immature sperms are being ejaculated.

I have a question…you mentioned it takes about 72 days for sperm to mature… if I have frequent sex, all of my mature sperm will run out???

Do I have to wait 72 days without intercourse and then I will have fully mature sperms? Shady Grove Fertility, please answer my questions: 1.

After 46 years old, I discover that my urge to have sex drop to once every 2 weeks instead of times a week.

Is this due to my sperm reproduction? The penis is not as hard as in the past and cannot maintain for 5 mins. I nowadays sleeping at 1 am instead of before 12 midnight in the past.

Viagra and Cialis do not help. Any natural remedy? Dear ShallowHal only one mature sperm is enough to fertilize an egg. Hello Please help if you can!

My wife and I are trying to have our second baby. We were going to start trying tonight but we had a small incident where our microwave caught fire while we were out, not in use just wiring issue that caught the wires on fire.

I went in when the house had smoke and realized the microwave had partially melted from heat. So I inhaled some smoke and air born plastics from the melted microwave, not sure if this effects the sperm.

Should we wait the 74 days until the sperm is regenerated or are we being over catious. Thanks in advance!

Hi, I am very overweight and have some poor semen figures. If I star changing my lifestyle today and my diet will it take three months from now for my sperm to get better or three months from when I lose a significant amount of weight?

Also I hear conflicting things on how often you should have sex during ovulation and outside some say every day others say every other please clarify.

If I stop smoking and start taking supplements, can I improve sperm quality already in production, so to be ready in months? How does having sex affects broken bone and does having sex once a week affect your 74 days for getting mature sperm?

The next month and a half or so his count was 93 million for the second round. Is it normal to have such a drastically different sperm count within the span of a month and a half?

There are many factors that can swing the count, including changes to lifestyle and last ejaculation. Although likely nothing is wrong, you may want to talk with your nurse or physician to ensure that your husband is doing what he can to optimize his sample.

My husband took a sperm analysis which resulted in a low sperm count, can he improve his sperm count by taking Selenium and prenatal vitamins?

I have been following your responses. Also I hear zinc supplements or foods high in zinc like Oysters are the way to go to improve quality, motility and mobility of these swimmers.

Okay so it takes sperm approximately 74 days to mature. Because other articles state that after a week with no ejaculation, it can affect sperm motility.

Moreover, reduction in pulse pressure, occurring in the proximal one third of the coiled length of the internal spermatic artery.

Dietary deficiencies such as vitamins B, E and A , anabolic steroids , metals cadmium and lead , x-ray exposure, dioxin , alcohol, and infectious diseases will also adversely affect the rate of spermatogenesis.

Hormonal control of spermatogenesis varies among species. In humans the mechanism is not completely understood; however it is known that initiation of spermatogenesis occurs at puberty due to the interaction of the hypothalamus , pituitary gland and Leydig cells.

If the pituitary gland is removed, spermatogenesis can still be initiated by follicle stimulating hormone FSH and testosterone.

FSH stimulates both the production of androgen binding protein ABP by Sertoli cells , and the formation of the blood-testis barrier.

ABP is essential to concentrating testosterone in levels high enough to initiate and maintain spermatogenesis. Intratesticular testosterone levels are 20— or 50— times higher than the concentration found in blood, although there is variation over a 5- to fold range amongst healthy men.

The hormone inhibin acts to decrease the levels of FSH. Studies from rodent models suggest that gonadotropins both LH and FSH support the process of spermatogenesis by suppressing the proapoptotic signals and therefore promote spermatogenic cell survival.

The Sertoli cells themselves mediate parts of spermatogenesis through hormone production. They are capable of producing the hormones estradiol and inhibin.

The Leydig cells are also capable of producing estradiol in addition to their main product testosterone.

Estrogen has been found to be essential for spermatogenesis in animals. From Wikipedia, the free encyclopedia.
