Answers
Answer:
Gametogenesis is the production of gametes from haploid precursor cells. ... Individual germline cells are called germ cells. During the process of gametogenesis, a germ cell undergoes meiosis to produce haploid cells that directly develop into gametes.
Explanation:
its first question answer i hope its helpful
Answer:
1.
Gametogenesis is the production of gametes from haploid precursor cells. In animals and higher plants, two morphologically distinct types of gametes are produced (male and female) via distinct differentiation programs. Animals produce a tissue that is dedicated to forming gametes, called the germ line. Individual germline cells are called germ cells. During the process of gametogenesis, a germ cell undergoes meiosis to produce haploid cells that directly develop into gametes. Hence, in animals, meiosis is an integral part of gametogenesis.

Cryptorchidism is most easily diagnosed at birth, as scrotum is relatively large, there is minimal subcutaneous fat, and the cremasteric reflex is absent. It is extremely important to document whether the testes are palpable in the scrotum at birth or in the first year of life. In a boy less than 9 years of age with bilateral UDT, serum FSH should be measured.
3.
Inhibin is a protein secreted by the Sertoli cells in men and by the granulosa cells in women. It inhibits the synthesis and release of the follicle-stimulating hormone in the pituitary gland and reduces the hypothalamic LH - releasing hormone content.
4.
The accessory glands of the male reproductive system are the seminal vesicles, prostate gland, and the bulbourethral glands. These glands secrete fluids that enter the urethra
5.
Well, the main constituents of semen are 1) Seminal vesicles secretions 2) Sperm. Overall, Sperm constituents are as follows: 1) 2-5 % Sperm or spermatozoa . 2) 65-75 % seminal vesicles secretions (It include fructose, amino acids, and citrate etc).
